Description

Technical Field

[0001] This utility model relates to the field of decorative lighting technology, specifically to a blinking lamp. Background Technology

[0002] Inflatable models are commonly used to attract more customers in festive decorations, commercial atmosphere creation, and interactive installations. Current inflatable models are typically cartoon characters or animal models, some with decorative lights. However, the decorative lights used for inflatable models, or individual decorative lights, generally include static lights with static illumination and dynamic lights with simple flashing effects. Both lack dynamic expressiveness. Traditional dynamic lights often rely on mechanical rotation or fixed programmed on / off states, resulting in stiff and monotonous movements that fail to achieve a natural and soft mimicry effect like a blink. While existing LED control technology can achieve basic changes, it has limitations—a lack of precise control over details such as rhythmic randomness and gradual changes in form—leading to stiff lighting expressions, weak emotional communication, and a lack of biological dynamism.

[0003] Especially when used for inflatable animal or cartoon characters, developing more vibrant lighting products would attract more customers and bring greater foot traffic to businesses. Utility Model Content

[0027] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. The present utility model will be specifically described below with reference to specific embodiments.

[0028] This utility model embodiment provides a blinking light, see reference. Figures 1 to 7The device includes a lamp housing 1, a circuit board 2, and a light source 3 mounted on the circuit board 2. The lamp housing 1 includes a circular, elliptical, oblong, or similarly shaped annular component 1a, a back plate 1b, and a light-transmitting top cover 1c. The annular component 1a defines the outline of the eye and has a surrounding wall with a certain height corresponding to the thickness of the lamp housing 1. The light source 3 is located on the back plate 1b of the lamp housing 1 and emits light upwards. The lamp housing 1 has a hollow structure, and the bottom back plate 1b can be directly fixed to the surface of the inflatable product by adhesive or other fixing methods. The lamp housing 1 better simulates the eyelid outline while preventing easy puncture of the inflatable product and providing a certain degree of fixation and protection for the built-in light source 3. This inflatable product can simulate various animal shapes, and the blinking lamp of this application is symmetrically positioned at the eye positions of the animal shapes. The light-transmitting top cover 1c is made of a light-transmitting material, and the cover body can be a membrane structure or a plate structure, preferably a plate structure. The translucent cover 1c allows the blinking light to transmit light while also being waterproof. The translucent cover 1c is detachably connected to the annular component 1a; specifically, the two interlock according to the snap-fit ​​positions on the back plate 1b. Assembly is simple and quick, and in one embodiment, the interlocked components form a waterproof structure. The cover portion of the translucent cover 1c has a slightly convex outward curve to simulate the structure of an eye, making it look more realistic.

[0029] refer to Figure 3 and Figure 7 The annular component 1a contains multiple roughly parallel partition plates 4. The two ends of each partition plate 4 are engaged and fixed to the inner wall of the annular component 1a, and the lower part of each partition plate 4 is tightly pressed against the back plate 1b, preventing light from passing through. These partition plates 4 divide the lamp housing into multiple light-emitting chambers 5. Multiple light sources 3 are evenly distributed within each of the multiple light-emitting chambers 5, with each light source 3 located at the center of its corresponding chamber 5. This design ensures that the light from each light source 3 in each chamber 5 does not interfere with each other. The switching of the multiple light sources 3 is controlled by a control chip (IC control module) on the circuit board 2. Through a preset program in the control chip, the light from each light source 3 is controlled individually, allowing the entire lamp to achieve regular, continuous (intermittent) switching effects, simulating the action of closing and opening eyes. It can also control the multiple light sources 3 to open slowly, remain constantly on / closed, or open quickly, varying the blinking speed and making the effect more dynamic and less rigid. In one embodiment, refer to... Figure 3 In the process, the first light source in the bottommost chamber illuminates first, while the light sources in the other chambers remain off. After 0.5 seconds, the light source above the first light source begins to illuminate, followed by the light source in the third chamber after another 0.5 seconds. Finally, the light source in the topmost chamber illuminates after yet another 0.5 seconds, creating the effect of open eyes. Conversely, to achieve the effect of closed eyes, the light source in the topmost chamber extinguishes first, followed by the light sources in adjacent chambers at equal time intervals, until all light sources are extinguished. These time intervals can be adjusted as needed, but are preferably between 0.5s and 2s.

[0030] For a more specific description of this application, see references. Figure 5 and Figure 7 A light-transmitting plate 8 (which can be a screen-printed sheet) with an eye pattern can be placed inside the curved lamp housing 1. The light-transmitting plate 8 is between the partition plate 4 and the light-transmitting cover 1c. The light emitted by the light source 3 first passes through the light-transmitting plate 8 and then through the light-transmitting cover 1c, so that the eye pattern can be seen. With the help of multiple graded light sources 3, it looks like a blinking eye to the naked eye, giving the light a vivid sense of life.

[0031] The circuit board 2 is mounted using the mounting bracket 6, see reference. Figure 2 , Figure 6 , Figure 4 and Figure 7 The mounting bracket 6 is located below the back plate 1b, protruding slightly backward and fixed relative to the back plate 1b. The circuit board 2 is first fixed to the mounting bracket 6 with two screws, and then the mounting bracket 6 is fixed to the periphery of the mounting opening in the back plate 1b with four screws, thus installing the circuit board 2. The mounting bracket 6 also protects the circuit board 2, and the circuit board 2 does not need to be directly mounted on the curved lamp housing 1, making it easy to replace in case of failure without damaging the main body of the curved lamp housing 1. The mounting bracket 6 has a pre-drilled wire hole 9 through which the power wiring on the circuit board 2 passes. A protective ring 10 can be installed around the wire hole 9 to protect the part of the power wiring passing through the wire hole 9, preventing damage to the insulation of the power wiring due to large bending angles. The wire extending from the wire hole 9 can be connected to external AC power or a battery.

[0032] Specifically, the number of light sources 3 corresponds to the number of light-emitting chambers 5, with four in total; and each light source 3 is distributed in the center of one of the four light-emitting chambers 5. The light source can be a lamp bead, a light strip, etc., and can be an LED lamp. For LED lamps, they can be copper wire lamps or lamps with other structures.

[0033] In one embodiment, the circuit board 2 integrates the following modules: an input module, a power supply step-down module, an MCU control module, and a load output module, as shown in the specific circuit structure. Figure 8 As shown.

[0034] In the input module, a current-limiting resistor R1 and a diode D1 are connected in series at the power input terminal. The current-limiting resistor R1 is used to limit current and buffer impedance to prevent high voltage surges. The diode D1 is a unidirectional conducting element used to prevent the circuit from reversing (conducting normally when connected in the forward direction; cutting off current when connected in the reverse direction), playing a protective and isolation role to prevent reverse power supply polarity and overcurrent surges.

[0035] In the power supply step-down module, the input voltage is converted into a safe operating voltage required by the control chip and the light source 3 via a step-down chip U1, supplemented by an input filter capacitor C1, an output filter capacitor C2, and a current-limiting resistor R2. The current-limiting resistor R2 is used to limit the current flowing into the input terminal of the step-down chip U1 to prevent the step-down chip U1 from being damaged by overcurrent. The input filter capacitor C1 is used for input filtering, filtering out low-frequency noise and ripple on the power line to provide a more stable input voltage for the step-down chip U1. The output filter capacitor C2 is used for output filtering, filtering out high-frequency switching noise and ripple at the output of the step-down chip U1, to provide a stable DC voltage for the subsequent control chip and the light source 3.

[0036] In the MCU control module, the control chip U2 has a built-in program algorithm that generates control signals according to preset algorithm logic to precisely control multiple light sources 3. Figure 8 The system contains four light sources (L1-L4); peripheral components include a current-limiting resistor R3 and a capacitor C3. The current-limiting resistor R3 limits the current flowing through the control chip U2 and the light source 3, preventing overcurrent burnout of the light source 3 and protecting the control chip U2 from damage by excessive sinking / sinking current. The capacitor C3 provides the instantaneous current required for the control chip U2 to start up, stabilizes its power supply voltage, and prevents abnormal operation of the control chip U2 due to poor power-on reset or voltage drops.

[0037] In the load output module, multiple light sources 3 (L1-L4) are LED lights, which are connected in series with a current-limiting resistor (R3) to the output terminal of the control chip U2. The control chip U2 controls their on / off sequence, gradation speed and action combination to achieve various blinking effects.

[0038] This application also relates to an animal model including the aforementioned blinking light, which is typically an inflatable model used to attract customers at the entrance of a shopping mall.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the principles of the present utility model should be included within the protection scope of the present utility model.
